INTERSECTION ENTRY CONTROL METHOD AND INTERSECTION ENTRY CONTROL SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an intersection entry control method and an intersection entry control system capable of reducing rear-end accidents before an intersection by accurately predicting the entry of a vehicle to a predetermined area (dangerous zone) before the intersection, reporting the effect to a driver of the traveling vehicle before a signal changes to yellow display, and increasing or decreasing the display time of a green signal or increasing or decreasing the speed of the vehicle.;SOLUTION: In the intersection entry control method for reporting, in the case that the vehicle enters a predetermined area before the intersection, this effect at a predetermined point of time before the vehicle entries to the predetermined area, the vehicle comprises a speed sensor, the traveling speed of the vehicle and a distance to the intersection are acquired based on a detection value of the speed sensor, it is determined whether or not the vehicle enters the predetermined area based on the acquired traveling speed and the distance to the intersection, time information for the end of the blue display of a signal in the intersection, and the position information of the predetermined area, and when it is determined that the vehicle enters the predetermined area, the blue display time of the signal in the intersection is increased or decreased.;COPYRIGHT: (C)2006,JPO&NCIPI
